Hello, I have a 1.1.2 OTB Iphone, I corrently have it unlocked with a *sim and in 1.1.2 fw. I understand that Geohot or Zibris Unlock works with any 1.1.2 or 1.1.3 OTB Iphone.
So is it safe to upgrade the fw from 1.1.2 to 1.1.3 using Itunes and then using Zibris unlock?? Or do I have to unlock using 1.1.2 and then use the devteam 1.1.3 official upgrade? Any difference in between each method?

Another question, if I upgrade using Itunes to 1.1.3 (and then unlock) my baseband would go to the newest one, and the location funcition on Maps would work as intended? No more using locate me or navizon??
